“…In this regard, the development of a standardized instrument similar to the OSIVQ that can be used by the blind and visually impaired could be of crucial importance. Moreover, it seems relevant to explore whether rehabilitative approaches for blind people should be tailored to these individual preferences and skills in order to implement more effective strategies for dealing with the environment (Kuyk et al, 2004). For instance, rehabilitation programs including orientation and mobility training and favoring coding of the environment based on its spatial features instead of verbal descriptions might foster more efficient spatial representations in those with inherent preferences for spatial imagery, whereas individuals more inclined to object imagery or verbal coding strategies might benefit from alternative approaches.…”

Previous studies have reported inconsistent results when comparing spatial imagery performance in the blind and the sighted, with some, but not all, studies demonstrating deficits in the blind. Here, we investigated the effect of visual status and individual preferences ("cognitive style") on performance of a spatial imagery task. Participants with blindness resulting in the loss of form vision at or after age 6, and age-and gender-matched sighted participants, performed a spatial imagery task requiring memorization of a 4 × 4 lettered matrix and subsequent mental construction of shapes within the matrix from four-letter auditory cues. They also completed the Santa Barbara Sense of Direction Scale (SBSoDS) and a self-evaluation of cognitive style. The sighted participants also completed the Object-Spatial Imagery and Verbal Questionnaire (OSIVQ). Visual status affected performance on the spatial imagery task: the blind performed significantly worse than the sighted, independently of the age at which form vision was completely lost. Visual status did not affect the distribution of preferences based on self-reported cognitive style. Across all participants, self-reported verbalizer scores were significantly negatively correlated with accuracy on the spatial imagery task. There was a positive correlation between the SBSoDS score and accuracy on the spatial imagery task, across all participants, indicating that a better sense of direction is related to a more proficient spatial representation and that the imagery task indexes ecologically relevant spatial abilities. Moreover, the older the participants were, the worse their performance was, indicating a detrimental effect of age on spatial imagery performance. Thus, spatial skills represent an important target for rehabilitative approaches to visual impairment, and individual differences, which can modulate performance, should be taken into account in such approaches.

“…For example, Engel et al and Kuyk et al demonstrated significant improvements in mobility-related ADLs after specific orientation and mobility training programmes, although it was not possible to calculate effect sizes from the data presented. 52,87 Horowitz et al reported small to medium effect sizes for functional outcomes in a large group of participants (N=395) after completion of a group based 'Adaptive Skills Training Programme'. 73 Farish and Wen found large effect sizes, particularly for near work, daily living skills and communication skills, in their evaluation of outcomes of 57 older people undergoing another new service, the "Independent Living Services Programme" for older persons in Mississippi.…”

“…141 Despite the conflicting evidence, overall it seems that the larger effects reported in the literature tend to come from intensive rehabilitation programmes e.g. 87,143 , although other studies have shown that it is possible to obtain a medium or large effect size with a relatively low dose intervention. 61,144 …”

This is the unspecified version of the paper.This version of the publication may differ from the final published version. Permanent repository link Abstract.Visual impairment is a large and growing socioeconomic problem. Good evidence on rehabilitation outcomes is required to guide service development and improve the lives of people with sight loss.Of the 478 potentially relevant articles identified, only 58 studies met our liberal inclusion criteria, and of these only 7 were randomized controlled trials. Although the literature is sufficient to confirm that rehabilitation services result in improved clinical and functional ability outcomes, the effects on mood, vision-related quality of life (QoL) and health-related QoL are less clear. There are some good data on the performance of particular types of intervention, but almost no useful data about outcomes in children, those of working age and other minority groups. There were no reports on cost effectiveness. Overall, the number of well designed and adequately reported studies is pitifully small; visual rehabilitation research needs higher quality research. We highlight study design and reporting considerations and suggest a future research agenda.

“…There is no standardized assessment of low vision O&M 3 , but the O&M research literature is dominated by a few approaches, with a combination of variants of walking speed and obstacle avoidance contacts being the most common 4,5 . It is also a common approach to seed the environment with obstacles, increasing the opportunities for detection/avoidance/contact 6,7,8 .…”
